Inverter Interface Board
The Inverter interface board provides interface to drive up the high current
consumption panel inverter in excess of 3.5A. This board enables current of up
to 8 Amps to be managed safetly while retaining the capability for inverter
dimming and management of the inverter enable signal according to VESA
DPMS standards. Additionally, the inverter interface board provides over-
voltage protection via a resettable fuse when the input voltage exceeds 13V
and reverse polarity protection against accidental misconnection.
